What is engineering design?
a problem-solving process that uses scientific knowledge, resources, and existing products to create new goods and processes
sequential engineering design process
Traditional engineering design process
What is the first step in the Traditional Engineering Design Process?
Define The Problem
PDM
Product data management software
These make up the concurrent engineering design process
Ideation, Refinement, Implementation
Name the two Problem identification techniques
Benchmarking: Get the best product available Base performance specifications for new product on it
Reverse Engineering: Dismantle and inspect competitors product(s) Select features to incorporate into new product
What is the Concurrent Engineering Design process?
Collaboration between all individuals, groups and departments within a company.
What is the second step, after defining the problem?
Traditional (sequential) engineering design process
Do background research
PLM
Product life cycle management software
Segments of Implementation: (There are 7)
1)Planning 2) Production 3) Marketing
4) Finance 5) Management 6) Service
7) Documentation
a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project.
Critical path method (CPM)
The purpose of this in the concurrent engineering design process is to test physical functions of the preliminary design Test if preliminary design meets requirements of specifications Determine manufacturing process.
Refinement
The Traditional engineering design process is a linear flow chart. True or False
True
CAD
Computer-Aided Design
Segments of Refinement (4)
1)Modeling 2)Design Analysis
3)Design visualization 4)Manufacturing Simulation
Product vs. System Design
Product design: process for creating new products
System design: process for creating a new system or process
This process helps evaluate preliminary design ideas against design criteria
Decision matrix
After testing the solution, the solution only partially meets the requirements or not at all. What is the next step?
(Traditional engineering design process)
Based on the results and data, make design changes, prototype, test again, and review new data
CAM
Computer-Aided Manufacturing
Segments of Ideation
1) Problem Identification 2) Preliminary Ideas
3) Preliminary Ideas
What kind of chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes representing events in the project linked by directional lines representing tasks in the project.
Project evaluation and review technique (PERT)
Which design process do most engineers use today?
Concurrent
What is the final step in the Traditional Engineering design process?
Communicate Results
CAE
Computer-Aided Engineering
Why Concurrent Engineering?
Give Reasons:
Reduces/eliminates repetition of tasks
Reduces waste and reworking of design
Leads to efficient engineering practices
